Fuse hydrogen into a living star. Grow it. Then blow it up — on purpose. SUPERNOVA is a premium-feel idle game about running a cosmic forge. Tap to spark fusion, build 12 generators from Hydrogen Wisp to Singularity Seed, and watch your star physically evolve — protostar, blue giant, red supergiant — until it is ready to collapse. Detonating it is the point: every supernova grants Neutron Cores, permanent power that makes each new universe faster than the last. WHY YOU'LL STAY • Real progress while you're away — production continues offline (extend the cap up to 24 hours with research), and a welcome-back doubler greets your return • A star that actually changes — five visual stages, rendered live, no canned art • Prestige that feels like a finale — a hand-built supernova cinematic, then a stronger start • Numbers that get gloriously big — Million, Septillion, and far beyond • Milestones every few minutes early on, deep multiplier stacking later • Daily missions and streaks that respect your time • 20 research upgrades that shape every run FAIR BY DESIGN • No ads. None. • No energy bars, no forced waits, no progress walls • Fully offline — no account, no sign-in, no internet required • Nothing collected, nothing tracked • Optional purchases exist (time warps, photons, a one-time Supporter Pack), and the entire game is balanced to be completed without spending anything THE LOOP 1. Tap your star and let generators forge Stardust 2. Hit ownership milestones — each one doubles a generator's output 3. Buy research, stack a Photon Surge boost, fill your Piggy Bank 4. Reach collapse readiness... and go SUPERNOVA 5. Keep your Neutron Cores forever. Start again, faster. Built by a solo developer in SwiftUI and SpriteKit. Every pixel is procedural — no asset packs, no stock art. Dark theme, tuned haptics, Reduce Motion respected. Your first universe is waiting. It starts with one atom.
